It may also be due to the use of automated follow-those-who-follow-me tools. I think a lot of twitter users immediately and reflexively follow you when start following them, but then after some time passes unfollow you if your tweets are deemed noise (in terms of what THEY are interested in).
Basically, I just got overwhelmed. I'm also tired of all the political Tweets.
I use this thing called Qwitter that lets me know when someone unfollows me, and all 3 were on the same Tweet which I sent - "Falling sick on your off day sucks". Either they have an aversion to the word "sucks" or they just didn't want to know that I was ill. :)
But I'm warning you now: if I see a tweet about how great Tony LaRussa and the Cardinals are, I'm out!
